MXC-T120ine simbachinowedzera simba re organotin geliyo inopa kugadzikana kuri nani mumhepo uye inovandudza mashandiro e polyurethane formulations. I catalyst inobva ku dibutyltin ine catalytic activity yakakura uye hydrolysis yakasimba, zvichiita kuti ive yakakodzera kushandiswa mumafomura e polyurethane egauyefuro rakasimba repolyurethane.
Chii chinonzi Organotin Gel Catalysts?
Organotin gel chinowedzera simbaimusanganiswa we organotin unoshandiswa zvakanyanya mukugadzira furo re polyurethane, machira, ma adhesive uye elastomers. Ma catalysts aya anoita basa rakakosha mukukurumidzisa maitiro emakemikari panguva yekugadzira polyurethane, kunyanya mukusimudzira maitiro e gelation (kana kuporesa). Ma catalysts akajairika e organotin, akadai sedibutyltin dilaurate (DBTDL)uyestannous caprylate, dzine basa rakasimba rekugadzira zvinhu, zvichiita kuti dzive nzvimbo dzemakemikari akakosha mumaindasitiri akasiyana-siyana, kubva pakuvaka kusvika pakugadzira mota.
MXC-T120 yakanaka kwazvochinowedzera simba re organotin geline kugadzikana kwakanaka kwemhepo uye kuramba hydrolysis, zvichiita kuti ishande kwenguva refu uye yakavimbika munzvimbo dzakaoma. Basa rayo guru mukugadzirwa kwepolyurethane nderekukurumidzira kuita pakati peisocyanatesuyepolyols, zvinhu zviviri zvakakosha pakugadzira furo repolyurethane.
Maitiro Ekuita SeiZvigadziriso zvePolyurethaneUnoshanda muRigid Polyurethane Foam?
Mukugadzirafuro rakasimba repolyurethane, ma catalysts akaita seMXC-T120 akakosha kudzora zvakanyatsonakamwero wekuita kwema isocyanates ane polyols nemvuraKuita kwakaringana kunoita kuti furo rive nehukuru hwakakwana, chimiro charo chakasimba, uye hunhu hwekudzivirira kupisa hunoenderana nefuro rakasimba repolyurethane.
Mafuro epolyurethane akasimba anoshandiswa zvakanyanya mumapaneru ekudzivirira kupisa, firiji, uye zvinhu zvekuvaka, uko kusimba uye kuputira zvinhu zvinonyanya kukosha. MXC-T120 inoita kuti igare yakapfava uye yakafanana, zvichiita kuti furo rigare kwenguva refu uye rinoshanda zvakanaka risina marara akawanda kana kuti rakakanganisika.hunhu hwe gelationita kuti ive yakakodzera zvakanyanya kushandiswa kunoda kugadzika nekukurumidza uye zvisungo zvakasimba zvekunamira.
MXC-T120: Mhinduro Yakanakisisa Yekushandisa Polyurethane
Mushonga weMXC-T120 unobva padibutyltin une kugadzikana kwakanyanya kwehydrolytic kupfuura zvinokonzeresa organotin, zvinoreva kuti unoshanda zvakanaka kunyangwe munzvimbo dzakanyorova. Izvi zvinoita kuti ive chikafu chemakemikari chinonzwisisika chekushandisa munzvimbo dzakanyorova kana dzakaoma, senge insulation yekunze kana Marine foam.
Nekushandisa MXC-T120, vagadziri vefuro repolyurethane rakasimba vanogona kuwana kurongeka kwakanaka kwechigadzirwa, kugadzira zvinhu nekukurumidza uye kushanda zvakanaka kwefuro.
Kambani yeMingxu Chemical yave ichigadzira macatalyst epolyurethane kwemakore anopfuura makumi maviri, tine nzira yakanakisisa yekushanda uye timu yehunyanzvi yekugadzirisa nekugadzirisa zvigadzirwa zvecatalyst pamusika, kune vatengi vakawanda, tinogamuchira vatengi kuti vauye kuzobvunza.
